In the case of a building, the soil is used as the ground on a ship. The installation of a lightning counter above the protective tube is recommended to perform the verification and maintenance of the facility. lightning rod, metallic rod (usually copper) that protects a structure from. 4 down conductors will be necessary for buildings higher than 60. Copper Grounding Rods CopperGroundingRods Copper Bonded ground earthing grounding. Protect the bottom of the downspout by a protective tube of at least 2 m. According to UNE 21186 / NFC 17102: Each PDC will be connected to the ground by 2 downspouts. See more ideas about lightning, grounding rod, earthing grounding. The downspout ground shall be properly secured and tightened, with reference driver three clips per meter. Those indicated in table 5 are the most recommended materials. The lightning rod and the attached cable and ground pole provide a low resistance pathway from the region above the building to the ground below. When several ESEs are installed on the same building they can share down conductors.ĭue to the nature of the lightning strike, down conductors should respect the materials and dimensions specified in IEC 62561-2. Meeting grounding safety requirements for electrical substations. Protection of central communications, electronics, and AC power systems. Prevention of accidents caused by static charge and stray currents. Its path must be as straight as possible, using the shortest path to earth, avoiding any sharp bend or lift. The Chem-Rod improves reliability for many applications, including: Lightning protection systems. The down conductors must be installed outside the building, avoiding the proximity of electrical cables and gas. The electrical earth ground rod is usually considered at zero volts. The lightning rod is connected to ground with at least two down conductors located on opposite facades whenever possible. The only purpose of a ground rod or a group of ground rods forming a ground field is to have a designed electrical path to dissipate a static discharge voltage (which can be lightning or other forms of static electricity) to the earth.
